Compute the nesting depth of departments
Description
The nesting depth of departments within a company is to be computed; see below for details. Let's assume that the management of the company is interested in the nesting depth as a simple indicator for the complexity of the company (or particular departments thereof) in the sense of a hierarchical organization. Nesting depth, together possibly with other metrics and information, could feed into the discussion of reorganizing business structures.
The nesting depth is computed as follows:
- The depth of a department is 1 + the maximum of the depths of its sub-departments.
- In particular, the depth of a department without sub-departments is 1.
- The depth of a company is the maximum of the depths of its (immediate) departments.
Motivation
The feature may be implemented as a query, potentially making use of a suitable query language. Conceptually, the required query is non-trivial in that it needs to process company structure recursively so that nesting of departments can be properly observed. For instance, it is not straightforward to design a Language:SQL query that computes indeed nesting depth on a normalized relational schema for company data. Thus, it shall be interesting to see how different software languages, technologies, and implementations succeed in realizing the feature.
Illustration
The feature is illustrated with a Function in Language:Haskell that works on top of appropriate algebraic data types for company data; the function recurses into company data in a straightforward manner and it counts departments along the way:
depth :: Company -> Int
depth (Company ds) = max' (map depth' ds)
where
max' = foldr max 0
depth' :: Department -> Int
depth' (Department ds ) = 1 + max' (map depth' ds)
The snippet originates from Contribution:haskellComposition.
Relationships
- See Feature:Total for a simpler query scenario.
- Indeed, the present feature should be tackled only after Feature:Total.
- The present feature can only usefully instantiated on top of Feature:Hierarchical_company, as it assumes nesting of departments for non-trivial results.
Guidelines
- The name of an operation for computing the nesting depth of departments should involve the term "depth".
- A suitable demonstration of the feature's implementation should compute the depth of a sample company.
- See Feature:Total for more detailed guidelines on a query scenario, which apply similarly to the present feature.
